Issue

Windows VM see's disk queue length greater than 1 (as high as 20).
Applications are getting 'low' op counts (400 prior to NFS plugin installation, 40,000 after).
No resource bottlenecks are seen on storage.
Utilization and all metrics including latency values and network port statistics show no issues.
